EL7530IY

Overview

The EL7530IY is a monolithic synchronous step-down switching regulator manufactured by Renesas Electronics Corporation. It integrates power FETs to deliver an output current of 600 mA with an adjustable output voltage range from 800 mV to 5.5 V. The device operates from an input voltage supply between 2.5 V and 5.5 V, utilizing a fixed switching frequency typically around 1.4 MHz. Designed for surface-mount installation in a 10-lead MSOP package, it supports operation across a temperature range of -40°C to +85°C.

Feature Summary

• Integrates synchronous rectification for high efficiency in a compact footprint
• Includes internal compensation to minimize external component count
• Provides protection against short circuits and over-temperature conditions

Applications

• Portable test equipment
• Li-ion battery powered devices
• Small form factor modules

Procurement Notes

Verify the specific suffix designation carefully, as the base part number may correspond to tube packaging while tape-and-reel variants exist. Confirm end-of-life status and lead times through authorized channels due to discontinuation notices. Ensure compatibility with moisture sensitivity levels during storage and handling procedures.

Selection Notes

Select this component when a compact solution is required for low-power DC-DC conversion applications. Evaluate the trade-off between the integrated FET current rating and the thermal performance within the MSOP package. Consider the fixed switching frequency constraints regarding external inductor selection and electromagnetic interference filtering requirements.

Part Context

This regulator belongs to the EL7530 series of monolithic step-down converters. It shares architectural similarities with related models like the EL7535 but offers higher output current capabilities. The series targets portable electronics requiring efficient power management from single-cell lithium sources or standard 3.3V/5V rails.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Verify cross-reference availability directly with the manufacturer or authorized distributors.
